If you want to add a small number of contacts to the list, you can use the form, that allows you to add contacts one by one on the Add Contacts page. Open this page using one of two ways.
Go to Contacts -> Overview and click Add Contacts in the right upper corner.
2. Go to Contacts -> Add Contact.
Then select the second tab Add One by One.
The Email Address field is required, fill it in and click Add. If you wish, you can also fill in optional fields. To see custom fields click Show More Fields in the right bottom corner.
After you add all the contacts you want, click Ready? Go! in the right bottom corner.
Next, select the list to which new contacts will be added. You can create a new list by entering its name in the text box on the left side of the page or select an already existed one on the right side of the page to add contacts. After selecting the list click Save and Finish.
After creating contacts, a banner with a successful message will appear and the My Lists page will be opened.
NOTE: During the upload process, all duplicate and invalid email addresses (such as those containing typos and syntax errors) are automatically eliminated.
